The festival is set to take place on July 14th, 15th and 16th at the Toyota Park in Highland, IL with KISS headlining the opening night, Korn leading the lineup the second night and Ozzy closing out the final night.

Megadeth frontman Dave Mustaine had this to say in the announcement, "This year's Chicago Open Air festival is going to kick so much ass! I mean, KISS, Megadeth, Anthrax, and Rob Zombie?! If I wasn't playing, I would want to go just to be part of the party!!

Stone Sour leader Corey Taylor added, "We are beyond stoked to be a part of Chicago Open Air this year. If you've never seen Stone Sour before, you're in for a goddamn treat. If you HAVE seen Stone Sour before, forget what you're expecting. It's a whole new ballgame. See you all soon!"
